upper surface ; all the pale markings are, however, clearer, 

 more sandy yellowish, excepting those on the outer margin, 

 which are white; those towards the base are extended in a 

 diffused manner towards the base ; the spots crossing the 

 disk of secondaries are acutely hastate, diffused externally. 

 On the under surface the colouring and pattern more nearly 

 approach those of C. phihthea, but all the light areas are 

 wider and more sharply defined; the general colouring of 

 the primaries is clear buff, that of the secondaries pearl-white, 

 washed with sulphur-yellow on the inner half of the discal 

 and marginal white markings, and here and there over the 

 basal area much as in the secondaries of G. manco ; the apical 

 area and marginal spots of the primaries are also similarly 

 tinted. 



Expanse of wings 46-52 millim. 



Ecuador (Buckley). Two males, coll. Hewitson. 



From all its near allies this species may be distinguished 

 by its clearer brighter colouring both above and below, by 

 the sharp definition of the under-surface markings, by the 

 much wider and less crescent-shaped disco-submarginal spots 

 across the under surface of the primaries and the wider corre- 

 sponding belt of markings across the secondaries. Hewitson 

 confounded this species with C. modesta. 



2. Catasticta cinerea, sp. n. 



Primaries above ash-grey, with the veins and costal margin 

 broadly black ; outer fourth of the wings occupied by a broad 

 black border, crossed by a series of whitish-grey spots ; a 

 marginal series of minute white dots : secondaries with the 

 basal half ash-^rey irrorated with black; outer half black, 

 crossed by a series of whitish-grey spots ; a marginal series 

 of small sulphur-yellow spots. Body blackish; palpi with 

 two lateral white lines ; collar with a small yellow spot on 

 each side. Under surface nearly resembling that of C. uri- 

 ccecJuce, but the grey areas more slate-coloured, the yellow 

 markings deeper in tint, all the pale markings more sharply 

 defined and those crossing the primaries broader. 



Expanse of wings 65 millirn. 



Locality unfortunately not preserved. One male, coll. 

 Hewitson. 



This very fine species and the two following were con- 

 founded by Hewitson with C. uriccechece ; the present species 

 is, however, in some respects nearer to C. semiramis and 

 amastn's.
